Abstract (en)
The invention relates to a method of effecting a single joint between two pipes of the pipe-line type by means of explosion welding, without the pipes being displaced in axial direction. This is achieved by moving an inner peripheral body (9) for welding between the pipe sections, to the joining point with the aid of a displacement unit expandable in axial direction.
